Lenka

It matches the group of varieties for early harvest and is distinguished by the exquisite appearance of tubers.

Variety characteristic:

Lenka is a variety that is suitable for very early harvest and for cultivation under a plast/fibertex after tuber sprouting. Pre-sprouted tubers quickly build a compact and low canopy. Already 40 days after emergence Lenka achieves a very high marketable yield that significantly exceeds the yield of reference varieties. According to studies of the Research Centre for Cultivar Testing, Lenka was the best yielding variety among varieties applied and accepted for the official examinations and for the post-registration variety testing system in 2021. In addition to its high yield potential, Lenka is characterized by exceptionally beautiful tubers and a great taste of the culinary type AB/B.
